An orca has been found dead and stranded on the coast of Papa Westray in Orkney.
The whale is believed to have been around five or six years old when it died.
Orca pods in the area are closely monitored, with sightings and photographs being catalogued to keep track of their movements.
Research teams were able to identify the animal as 151, part of the 27s pod which can often be found in the waters around Orkney and Shetland.
Scottish Marine Animal Strandings Scheme (SMASS) announced the news on their Facebook page.
Emma Neave-Webb and Imogen Sawyer from Orkney Marine Mammal Research Initiative (OMMRI) attended the orca on Monday, September 6.
They took initial samples to begin trying to determine cause of death, including photographs and measurements.
A necropsy is due to take place on Tuesday to help with their investigation.
OMMRI asked that people refrain from commenting on the event until they have carried out their investigation into the health of the animal before it died.
In a post on their Facebook page, they said: “Whilst we understand and appreciate that this news is upsetting we ask people to please avoid speculation and comment at present. A full report will come from SMASS in due course.”
